Just a statement of fact here. I’ve seen a lot comments about the possibility that SWA may have just switched over from ground and might not have known about FDX. That’s not true. In the takeoff clearance, the TWR Controller advised FDX was on a three mile final. Simple math tells you that’s about 90 seconds from touchdown at 120 knots. You could make the argument they were distracted or go-oriented, but not that they were not informed.
